Plenty of people would stop worrying about money if they had a net worth of $2.3 million. That number dwarfs the median household net worth of $166,900, according to Census Bureau data, and it lands the earners comfortably in the 90th percentile of U.S. households. 

Nevertheless, a couple of very-well-off 37-year-olds recently wrote to money expert and self-made millionaire, Ramit Sethi, to express their financial angst. Both partners work in tech and together earn about $850,000 a year, Sethi told his readers in a recent newsletter. They have a combined net worth of $2.3 million with over $1.5 million in retirement and regular investment accounts.
